Cheaper than plumbing a fuel return line

Plus you sometimes get to see other cool cars filling up here during hot weather....

Price isn't too bad but I don't look for ethanol free gas for the Ventura, it's fine on 92-93 octane with 10 percent ethanol.

The key to success is to install parts in your carburetor that will hold up fine in any concentration of ethanol, then go on to worry about something else.

I've made those parts available and offer a lifetime warranty on them no matter what type of fuel you are using......FWIW.....

Yessir, I've recently switched to using your SR kits on both my personal and customer rebuilds.

I just have to run "E0" in the summer because my stock fuel system and brutal under-hood temperatures (idling in traffic with A/C running) can cause vapor lock in the fuel line and starve the carburetor...

would a return line remedy this?

[Cliff Ruggles]

I've never had any issues with fuel boiling in the carb but we do get a few emails and calls to the shop about it.  It's ALWAYS in the very hottest months and about 80 percent of the time from folks with early applications using factory intakes that had extra passages to route heat directly to the carb from passages leading down to the exhaust crossovers in the intake.....

Whats the octane on the real gas?  Where are you located?  Here in central Indiana we have some ethanol free from Country Mark, the oil wells are here in SW Indiana(!) and it is refined here also.   They charge about 10 cents more per gallon, and it is 90 octane.  I use it for all my small engines, and did in my 68 LeMans until recently.

Too Fast, I'm so jealous of your local hookup! I get my 90-octane E0 at a Marathon station in the suburbs of Cleveland, Ohio. I've been meaning to go visit some of the public marinas on Lake Erie to see if their pumps are accessible (from land) and if they offer better pricing...

we have shell 91 and chevron 94 with no ethanol where I live in Canada just above washington state. i've heard rumours that our fuel is different,not as good as what they sell down in the USA. i also run shell 91 in my small engine stuff.

Prior to Covid I travelled to Toronto from Chicago 4 to 5 times a year.  In all my rental cars, I never experienced any performance issues from Canadian gasoline.  It performed well and for that I am thankful.  Driving on the "Four-Oh-One" is challenging enough without worrying about gasoline quality!

[Cliff Ruggles]

In most states they are NOT required to tell you that Ethanol is in the fuel.  I wouldn't go out of my way looking for it anyhow.  I use ethanol fuel here, 10 percent and have for many years now with zero issues anyplace.  The key to success is using parts that will hold up in it, and if you are using it in small power equipment don't leave it in the tank for many months or years, but really all fuel goes stale in time.  So keep fresh fuel in your equipment and sleep better at night......FWIW....

I installed a WIX WIX 33040 Fuel Filter with a return line on my truck. I don't know if it needed it but it was easy enough to install and only cost a few bucks.

I’ve used the fuel filter also, up as close to the carb as possible, worked like a charm using the tank vent line as the return and leaving the gas cap loose.
I run mostly non E but want to be able to use 10% also.
Had problems with the vapor lock.
My 74 K5 Blazer did not come with a return. Never had any problems for years then bam there it was.
I added the return, replaced the tank sending unit with one that had  the return port. Used the 3 line fuel pump in place of the filter with the vapor return and didn’t help a bit.
From there I didn’t want the big filter so I added an inline barbed  fitting for an external Fuel pressure gage on the fuel line up near the carb with a 1/4 inch barbed elbow for the return. Installed a .060 restriction in the elbow like the Wix filter does.
Worked like a charm. Never a problem since.

Thank you guys for the part numbers and testimonials. I was thinking of converting an old tank vent line to a fuel return line as well. I've just been putting this off because I'm a bit neurotic about fuel safety, and want to be sure it's implemented properly...i.e. next winter when I have time to bend and flare some steel tubing.

[Cliff Ruggles]

I prefer and use a return on all older vehicles I've owned that were carbureted.  I know they tell us that most of these electric and mechanical pumps will work fine ran "dead-head", but it's just easier on the pumps to supply an alternate path for fuel flow.  If nothing else it takes some load off the pump and with electric pumps for sure they will run quieter and the brushes will last longer.........

Just remember if you use the existing vent line you have to vent the tank with a free flowing vented fuel  cap or the tank will pressurize from the fuel returning to the tank .
